Getting harder to find as some have started rusting out, Needs to be a Supersport one as the angle through the swingarm is different. One option would be to go with a 750 twin exhaust setup, same size headers with a 35mm diameter unlike the 900SS and Monsters which are 40mm. I have a set of 750SS (might be off the injection model) that you can have free of charge and as Brian Alexander is coming down from Scotland next week to Race at Pembrey we can easily get them north of the boarder
